This instruction was created to work around a problem with injecting a `ChangeDetectorRef` into a pipe. See #31438. This fix required special metadata for when the thing being injected was a `ChangeDetectorRef`. Now this is handled by adding a flag `InjectorFlags.ForPipe` to the `ɵɵdirectiveInject()` call, which avoids the need to special test_cases `ChangeDetectorRef` in the generated code. PR Close #41231
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules compiled with ngc, into node_modules which
appear to have been compiled with ngtsc.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
